Winterman | Extreme Triathlon Series 2026

Winterman is an extreme triathlon held in Decin, Czechia. The race route crosses Czech-Saxon Switzerland and the Lusatian Mountains, concluding atop Jested at 1,012 metres. Taking place in October, the full course follows a long-distance triathlon format: a 3.8 km swim, 180 km bike ride, and 42 km run. A half-distance option is available for athletes seeking the same demanding mountain-race character without the full route commitment. The course has rough terrain, extended durations, and a summit finish, contrasting with flat city races. Winterman emphasizes the athlete-support team dynamic, making the day a shared effort rather than an individual endeavor. GPS tracking and live results enable supporters to monitor the race's progression, a crucial feature for an event spanning mountains and border roads. The competition appeals to athletes seeking a comprehensive physical and mental challenge, particularly those drawn to extreme triathlon over standard mass-participation road events.
